Echinacea plant named ‘Pink Double Delight’

ABSTRACT

A new and distinct cultivar of  Echinacea  plant named ‘Pink Double Delight’, characterized by its upright and somewhat outwardly spreading plant habit; moderately vigorous growth habit; freely basal branching habit; and large single inflorescences with pink-colored ray florets and darker pink-colored disc florets.

Botanical designation: Echinacea purpurea.

Cultivar denomination: ‘Pink Double Delight’.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is related to U.S. Plant patent Appplication Ser. No. 11/527,811, Echinacea Plant Named ‘Pink Shuttles’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Echinacea plant, botanically known as Echinacea purpurea, and hereinafter referred to by the name ‘Pink Double Delight’.

The new Echinacea is a product of a planned breeding program conducted by the Inventor in The Netherlands. The objective of the breeding program is to create new compact Echinacea cultivars with unique inflorescence form and attractive ray floret coloration.

The new Echinacea originated from a cross-pollination in Bovenkarspel, The Netherlands in July, 2003, of a proprietary selection of Echinacea purpurea identified as code number Ec 201-01, not patented, as the female, or seed, parent with a proprietary selection of Echinacea purpurea identified as code number Ec 202-01, not patented, as the male, or pollen, parent. The new Echinacea was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled environment in IJsselstein, The Netherlands.

Asexual reproduction of the new Echinacea by micropropagation in The Netherlands since 2004, has shown that the unique features of this new Echinacea are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Pink Double Delight has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Pink Double Delight’. These characteristics in combination distinguish ‘Pink Double Delight’ as a new and distinct cultivar of Echinacea:

-   -   1. Upright and somewhat outwardly spreading plant habit.     -   2. Moderately vigorous growth habit.     -   3. Freely basal branching habit.     -   4. Large inflorescences with pink-colored ray florets and darker         pink-colored disc florets.

Plants of the new Echinacea differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Echinacea are more compact than plants of         the female parent selection.     -   2. Plants of the new Echinacea are more freely branching than         plants of the female parent selection.     -   3. Plants of the new Echinacea have smaller inflorescences than         plants of the female parent selection.

Plants of the new Echinacea differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Echinacea are more compact than plants of         the male parent selection.     -   2. Plants of the new Echinacea have thinner stems than plants of         the male parent selection.     -   3. Plants of the new Echinacea flower earlier than plants of the         male parent selection.     -   4. Plants of the new Echinacea have smaller inflorescences than         plants of the female parent selection.

Compared to plants of the cultivar Pink Shuttles, plants of the new Echinacea are more freely branching, more freely flowering and differ in inflorescence form.

Plants of the new Echinacea can be compared to plants of the Echinacea cultivar Razzmatazz, disclosed in U.S. Plant Pat. No. 13,894. In side-by-side comparisons conducted in Vleuten, The Netherlands, plants of the new Echinacea differed from plants of the cultivar Razzmatazz in the following characteristics:

-   -   1. Plants of the new Echinacea were more compact than plants of         the cultivar Razzmatazz.     -   2. Plants of the new Echinacea were more freely branching than         plants of the cultivar Razzmatazz.     -   3. Plants of the new Echinacea were more freely flowering than         plants of the cultivar Razzmatazz.     -   4. Plants of the new Echinacea had smaller inflorescences than         plants of the cultivar Razzmatazz.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Vleuten, The Netherlands during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Echinacea production. During the production of the plants, day temperatures ranged from −5° C. to 35° C. and night temperatures ranged from −8° C. to 20° C. Measurements and numerical values represent averages for typical flowering plants. Plants were about 16 months year old when the photographs and description were taken.
